Very brilliant man made fire opal inlayed in sterling silver. There are a few accents of onyx set in with the opal. The center piece is 2 1/2"x 1". The two sides are 1 1/2"x 1/2". The length of all three would be about 7" and the length with the chain is 22". It is signed sterling & has a small design after it which could be the artist signature.
